The Arizona Superior Court notes that soon after the capital was established in Tucson, “it was clear that the town needed a permanent courthouse, as county and territorial business was being conducted in a pair of rented rooms.”

To commemorate 150 years since Tucson began serving as Arizona’s capital, the Postal History Foundation in Tucson sponsored a pictorial cancel.

The Postal Service has also announced an addition to its Postmark America program, which features “graphics related to a theme or image that pertains to a specific tourist location, town or region.” These postmarks are available any day at the participating post office, and by mail.
